This Week's Guests:

• National Geographic Weekend goes looking for giant sea spiders with Martin Riddle. Riddle tells Boyd about this critter and others found as part of the expedition he led to Antarctic waters to take a census of marine life in the cold Southern Ocean. The expedition was part of the International Polar Year program.

• The Arctic is warming faster than any other place on Earth! Now, NASA is trying to find out why by flying planes around the North Pole to study the atmosphere. Boyd talks with Harvard professor of atmospheric chemistry Daniel Jacob about the project.

• Sometimes the girls just want to get away. Not to the mall, but to Nepal. Marybeth Bond has written a new book about getting away with the girls entitled Best Girlfriend Getaways Worldwide. Boyd talks with Bond about what both guys and girls can learn from this new book.

• World-renowned archaeologist and National Geographic Explorer-in-Residence, Zahi Hawass serves as Secretary General of the Supreme Council of Antiquities for Egypt. Hawass joins Boyd in the studio to talk about King Tut as well as exciting new discoveries of Egyptian antiquities.

• The average American will drink an astounding 43,371 cans of soda in his or her lifetime—that’s more than 2,000 cans opened every second in the U.S.! The Human Footprint, a new film from the National Geographic Channel and the Wildlife Conservation Society, examines consumption in America. Associate director of the WCS Eric Sanderson joins Boyd to discuss the film.

• Doug Fine left his suburban life for an off-the-grid adventure. Fine documents the trials and tribulations of going solar, raising goats and keeping his Funk Butte Ranch running in a new book called Farewell, My Subaru. Fine joins Boyd in the studio to talk about his successes and failures.
